G94 is the feed per minute mode, which is also the default mode of general systems
g95 is the feed mode per revolution, milling operation which is commonly used in rigid tapping

for example, in Frank format, intercept a main code. When using g95, the feed is equal to the pitch. After the fixed cycle is completed, enable G94 to prevent the milling cutter program behind tapping, resulting in "feed error"
